STOVE.

SPECIFICATION forming part Of Letters Patent N0. 628,272, dated July 4,1899 Application filed January 24, 1898. Serial No. 667,782. (No model.)

To aZZ whom, it 11110.3 concern.-

Be it known that 1, JOHN P. LYNOTT, of the city of Louisiana, Pikecounty, State of Hissouri, have invented certain new and usefulImprovements in Stoves, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

My invention relates generally to stoves, and more particularly to aheating stove of the downdraft variety; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

Figure 1 is a rear elevation of a stove constructed in accordance withmy invention. Fig. 2 is a side elevation thereof. Fig. 3 is a verticalsectional view taken approximately on the line 3 3 of Fig. 1. Fig. 4 isan enlarged vertical sectional view taken approximately on the line 4 4of Fig. 2. Fig. 5 is a view in perspective of a specially-formed box ofwhich I make use in my improved stove and which Iterm the draft anddamper box. Fig. 6 is a plan view of the body portion of the stove,showing the f u el-inlet and the draft-openings.

Referring by numerals to the accompanying drawings, 1 indicates the baseof my improved stove, which is oval in plan View, and said base isprovided with the cast bottom plate 2 and cast top plate 3. The body ordrum 4 of my improved stove extends upwardly from the top side of thefront portion of the top plate 3, said body or drum being provided witha suitable top plate 5, in the center of which is a fuel-inlet 6, closedby the pivoted plate 7, and in said top plate 5 is also formed a seriesof draft-openings S, which are adapted to be shut or closed by thesliding damper 9. Located in the lower end of the body 4 is the grate10, and immediately above said grate is the fire-box 11. Formed in thebody 4 of the stove at a point slightly below the upper end of thefire-box 11 is a continuous row of draft-apertures 11. Formed in the topplate 3 immediately behind the body 4 is an oval opening 12, which isbounded by the upwardly-projecting flange 13. Formed in the bottom plate2 below the opening 12 is a pair of air-inlets 14, the same beingbounded by the upwardly-extending flanges 15,formed integral with thebottom plate 2.

16 indicates a rectangular sheet-metal draft and damper box, the edge ofthe open rear end being provided with the integral flange '17, throughwhich flange passes the rivets or screws, whereby said draft and damperbox is securely fixed to the rear side of the upper end of the body 4,there being a rectangular opening 18, formed in the upper end of saidbody 4, that coincides with the open rear end of said box 16. Formed inthe bottom of this box 16 is a rectangular opening 19. Formed integralwith and projecting laterally from the lower edges of the sides of thebox 16 are flanges 20, and formed integral with and projectingdownwardly from the under side of this flange 20 and from the under sideof the box 16 is an oval flange 21, which is identical in size and formwith the upwardly-projecting flange 13. The lower end of the ovalsheet-metal cylinder 22 is located upon the upwardly-projecting flange13, while the upper end of said cylinder 22 is located uponthedownwardly-projectingflange21. Formed through the flanges 20, insidethe space bounded by the ends of the flange 21, are openings 23, theunder side of their edges being bounded by the downwardly-projectingflanges 24.

Suitable sheet-metal tubes 25 have their lower ends located upon theupwardly-projecting flanges 15 of the bottom plate 2, and the upper endsof these tubes 25 are located upon the flanges 24.

26 indicates a damper which is pivoted transversely in the bottom of thebox 16 at a point immediately in front of the opening 19 in the bottomof said box, and when said damper is turned upwardly it will close theopening 18. hen said damper 26 is turned downwardly, it will close theopening 19 in the bottom of the draft-box 16.

111 the operation of my improved stove when the fire is first kindledtherein the damper 26 is turned downwardly, so as to close the opening19. The smoke, flame, and products of combustion from the fire will nowpass upwardly through the upper end of the body 4 of the 'stove, outthrough the opening 18, through the draft box 16, and upwardly throughthe pipe that leads from the top of said draft-box to the flue; When thenewlykindled fire is well started and it is desired to manipulate saidstove so as to heat the air in which said stove is located, the damper26is turned upwardly, so as to allow free passage from the opening 19, andthis movement of the damper closes the opening 18. The damper 9 in thetop of the stove is now manipulated, so as to allow the required amountof draft to pass through the draft-openings 8, and said draft will passdownwardly through the fire, as indicated by the arrows, from thencethrough the grate 10 into the oval body 1, from thence upwardly throughthe oval cylinder 22, through the opening 19 in the bottom of thedraft-box, through said draft-box, and from thence out through thelength of pipe to the flue. This draft is greatly assisted by the draftthat enters the apertures 11 in the body of the stove 4 and mingles withthe first-mentioneddraft immediately beneath the grate 10. As fresh fuelis passed to the interior of the body of the stove through thefuel-opening 6 it will be consumed by the fire within the fire-box 11and the smoke, gases, and other products of combustion will passdownwardly through the fire and bed of coals which has been formed uponthe grate 10, and said smoke and other products of combustion willthereby be consumed and only the White smoke or certain unconsumablegases, together with the heat from the fire, will pass upwardly throughthe oval cylinder 22 and draft-box 16. As said heat passesupwardly'through the oval cylinder22 the tubes 25 within said cylinderwill become very thoroughly heated, and therefore the air which is takenfrom beneath the stove and which passes upwardly through said tubes 25will become very thoroughly heated and will be passed out through theopenings 23 in the flanges 20 in said heated condition.

The draft to the fire within the fire-box 11 is regulated bymanipulating the damper 9 and by also manipulating the damper 26, it

only being necessary to turn said damper 2G downwardly to close theopening from the damper-box to the oval cylinder 22, and thus the ovalcylinder 22 ceases to be a heatingdrum.

Thus it will be seen how I have constructed a very eflicientheating-stove, one which is simple in construction and requires but verylittle attention and which stove very readily and completely consumesthe products of combustion arising from the newly-fed fuel.

I claim- In a stove of the class described, the com bination with theoval base 1, the cylindrical body t mounted upon said base, in theupper' end of the rear side of which body is formedan opening, thecylinder 22 extending upwardly from the rear end of the oval base andthe tubes 25 extending upwardly from the body of said stove-base throughthe cylinder 22, of the removable draft-box 16 arranged against the rearside of the oval body of the stove over the opening therein, in the topand bottom of which box are formed alined openings, the flanges 20formed intogral with and extending laterally from the lower edges of thesides of said box, in which flanges'are formed openings, the upper endof the oval cylinder engaging against the under side of said flanges 20and the upper ends of the tubes 25 communicating with the openings insaid flanges, and the damper 26 pivotally arranged in the lower forwardcorner of the draft-box and adapted to close the opening in the bottomof said draft-box or the opening in the rear upper side of the stove.-body, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
